Yes, and no...

If you were to take a Tunnel Ram off of a Drag Race engine that is desgined to work at 10,000 RPM yes it would have a lag. If you design the package properly taking into consideration the heads, runner size, runner length, shape, plenum size, and carburetor sizes you won't have a problem at all.

YEP. Good answer. :Score-101010:

OK then- let's do a common test case-

540 ci, Crane 741, 9:1 comp, good aluminum heads (probably non-cnc)

This combo would probably have something like the Dart intake and a 1050 on it in a single 4 barrel configuration.

So in a TR setup, what manifold, what carburetors and why?

You'd really need the specific heads to see what's going to work best. If it were mine I would not use the same heads or cam as a single 4bl engine.

Believe it or not , the old Holley Pro Dominator tunnel ram works very well in a marine application with it's smaller plenum volume. I have a pair of 572 Donovan blocked T-ram engines in a 1990 Cigarette 38 Top Gun that runs 92-93 mph. They work great!

WEIAND 5885. Old school ram. put dual 4150flange 600CFM HiPo Holleys. Unless you are getting nasty with a cam over .680. Then use 750's

You can also use a single dominator on a Tunnel ram, but I have not, nor know anyone who has tried it.

Idle and docking has never been that big an issue. It seems that dock manners for me have always been in the camshaft and how much is left in the cooler.

I have a 582" engine with oversized combustion chambers that I built ffor a blower, but am actually probably going to put a Ram on, since I have one lying around. If I get around to it, I will post numbers.

Dr. Dean, how is my answer to Chris's test question?

So what carbs would you use on our hypothetical 540 motor? Is cam a consideration? If so, why?

I used this same basic combination on a 400" small block with fantastic results. Used 450's, not 600's.

NOT BAD JEFF ,P.M. me on those carbs if u still got em ..Leon get those heads done ??? he's suppose to call here at noonish
ROCK ON !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!

A true tunnel ram intake with a single 4bl is NEVER a good idea. You can have distribution issues. If you're going to run a single 4bl, use a single 4bl intake manifold.
